If you are making passwords and they start with 2 letters from the alphabet and end with 3 digits from numbers 0 through 9 how many possibilities are there?
676,000 possibilities.
For case-sensitive passwords, it's 2,704,000 possibilities.
Passwords consist of 2 letters and 3 digits. That's 5 places. The first and second places can each hold 1 of 26 possibilities (26 letters), and positions 3, 4, and 5 can each hold 1 of 10 possibilities. The answer is 26 x 26 x 10 x 10 x 10 = 676000.
Maybe the passwords can be case-sensitive (i.e. an upper case letter is different from a lower-case letter), then there will be 52 possibilities for each letter - in each of the 1st and 2nd places. This gives the total as 52 * 52 * 10 * 10 * 10 = 2,704,000.
Note: An assumption we made is that the passwords are only 5 characters, consisting of 2 letters and 3 digits only. The question didn't say that no other characters are between these letters and numbers. If there are, then we don't have enough info to answer the question.

720 is the number of ways to combine three known letters and three known numbers.For example, the letters A, B & C and the numbers 1, 2 & 3. The total combinations of these 6 characters is:(6 options)*(5 options)*(4)*(3)*(2)*(1) = 720.However, if the three numbers and three letters are unknown and any number or letter is possible, and repeated numbers or letters are acceptable (such as with a license plate), then the total possibilities for each "space" are multiplied together:(26 possibilities)*(26 possibilities)*(26 possibilities)*(10 possibilities)*(10 " ")*(10 " ") = 17,576,000 combinations.That is, there are 26 letters in the alphabet and 10 numbers (0 thru 9).This is assuming that three of the six spaces spaces are reserved for letters and three spaces are reservedfor numbers.If the combination can be any three letters and any three numbers where different combinations are made by changing whether each space contains a number or a letter, then the answer becomes a product and sum of different choose functions and is much more complicated...
